Distributed Energy System can satisfy user’s various needs (heat, cooling and electricity) while
reducing the efficiency loss during energy transportation.

Life Cycle Analysis Becomes a Main Stream of Evaluation Methods.

Investigates the difference of emission between Distributed Energy System and traditional energy system, providing insights about sensitivity factors like HPR (Heat-Power Ratio) and
discussing about several specific scenarios.

Case studies are demanded in both academic literature and policy-making because:

With output (electricity, heat and cooling) held constant, we analyzed the input required by different technologies and compared life cycle energy consumption and GHG emission. By comparing the results of these cases and doing sensitivity analysis.

In order to contemplate all the environmental aspects to an organization, it must consider:

Standards NTC ISO 14040 and ISO 14044 allow to guarantee the accomplishment of the applicable requirements, in the lifecycle analysis (LCA) evidencing evaluation and control of the inputs, the outputs and the potential environmental impacts of the product through its lifecycle.

 

 

They are all activities necessary for the extraction of raw materials and energy inputs from the environment, including transport before the production. This is included in the environmental aspects and impacts matrix in energy consumption processes as well as in all aspects where natural resources are used.

Activities necessary to convert the raw materials and energy in the desired product, also must be included in the environmental aspects and impacts matrix to ensure the control as well as the impacts associated to the transportation.

Transport of the final product to the customer, associated to the impact generated by the emissions of pollutants produced by different vehicles used for this activity and increases due to the growth of the market and the need to achieve sustainable development.

The use of the finished product throughout its service life must be controlled with a methodology that guarantees the use of recyclable waste to dispose in small quantities.

Once the product served for its initial function begins and consequently its recycled through the same product system (closed recycling cycle) or get in to a new product system (open recycling cycle). Programs must be implemented to comply and guarantee the control indicating the waste generated, if recycling is applied or not and what type of disposal will be the most appropriate.

Once the product has served its function and it is returned to the environment as a waste must be collected and limited according to the polluted and hazard degree, to avoid affecting waste that can be transformed for recovery, so that way they do not represent damages or risks to the human health and the environment.

The scope definition should include: 

Energy Consumption and GHG Emission – A Case of Beer Brewery Auxiliary Power Supply in China, I believe that a life cycle according to the NTC focuses on the definition of a goal and scope, based on an analysis of inventory which is evaluated through an impact, obtaining as a result the development and product improvement, strategic planning, public policy setting, commercialization, among others.

That is why reading as the main theme of the use of natural gas for the implementation of projects, aims to have a large scope for the reduction of energy and GHG.

In my opinion it is a very successful proposal since it contributes to the mitigation of GHGs and offers alternatives for the use of sustainable technologies that help preserve the environment.

Consistency check

Process of verifying that the assumptions, methods and data are consistently applied throughout the study and are in accordance with the goal and scope definition performed before conclusions are reached.
